HDPE 100 Potable water pipe
“When choosing pipes to carry water for human consumption, these pipes must meet or exceed every standard.”
With customer satisfaction and health being the number one priority in our production process, Sarkis Co ensures that our manufactured pipes meet the highest standards available which can be applied for designing long-term loaded PE pipes networks operating at a temperature of 20°C for a designed life of at least 50 years. Our pledge to contentment, our strict manufacturing practices, and our perfect attention to quality make Sarkis Co the favored choice for potable water applications.
Selection of raw material applied for PE pressure pipe for water supply
Classification and designation
The basic polyethylene (PE) material types used for HDPE pipe production are PE 63, PE 80 and PE 100.
The classification number of PE is to identify the pressure that the plastic materials can resist. Referring to ISO/TR 9080, it is based on the minimum required strength (MRS), which has to be applied for designing long-term loaded PE pipes operating at a temperature of 20°C for a designed life of at least 50 years.
Elasticity and preservation
High density polyethylene PE 100 material, with bimodal distribution of molecular mass, is specifically designed for pressure pipe applications, it provides excellent stress crack resistance properties (ESCR) combined with very good long-term hydrostatic strength, even at low temperatures down to minus 20°C.
Characteristics
High density polyethylene PE 100 material, being the latest discovery in the world of polyethylene after PE 80, gives the pipe an additional advantage to have the thinness wall with the highest resistance, which means more water flow with the same outside pipe size.
Effect on water quality
High density polyethylene PE 100 pipes are suitable for drinking water. Due to the high-quality material used in our pipes, it has no effect on water taste, odor, appearance of water, and growth of aquatic micro-organisms.
Color of pipes
HDPE pipes for water use are supplied in two colors: totally blue or black with blue stripes.
Note that other stripe colors are co-extruded with black pipe, to designate the usage, for example: orange stripes for conduit and yellow stripes for gas application.
Pipes specifications
HDPE 100 pipes dimensions are manufactured according to ISO 4427, DIN 8074/8075 and EN 12201 standards.
The pressure rating of a pipe (PN) is determined by the diameter, wall thickness and material type at a given temperature, and is expressed as:
PN bar – pipe pressure rating at 20°C (Mpa x10)
